JOHN B. YARNELL AND FRANK MER'IZ, OF J OI-INSTOWN, PENNSYLVANIA.

HOSE-COUPLING.

Application filed June 2S, 1916.

To all whom it may concern:

Be it known that we, JOHN B. YARNELL and FRANK MERTZ, citizens of the United States, residing at Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification.

Our invention has relation to new and useful improvements in hose couplings.

An object of the invention is to provide a coupling that will be adapted for use upon either garden, air or fire hose or any hose that is employed to conduct a fluid.

A further object of the invention is to provide a coupler of the above nature that will be quick-detachable.

Further objects of our invention are to provide a device of the above characteristics that will be simple in construction, durable in use, efficient in operation and one which may be easily and inexpensively manufactured and installed.

\Vith the foregoing and other objects in view our invention consists of the novel features of construction, combination and described in this illustrated in the accompanying drawings forming a part thereof, and particularly pointed out in the claims hereunto appended.

Reference being had to the drawings:

Figure 1 is a plan of the device.

Fig. 2 is a side elevation thereof. 7

Fig. 3 is a plan view of the inner face of one section of our invention, parts broken away and partly in section.

Fig. 4; is a plan view of the inner face of the opposite section.

Fig. 5 is a vertical longitudinal section of the entire coupler.

Fig. 6 is a plan view of a modified form of our invention.

Figs. 7, 8, 9 and 10 show a modified form of the invention.

Referring more particularly to the drawings, in which like numerals designate like parts throughout, our invention is described as follows:

The coupler comprises two sections 1 and 2 which, when connected together, interlock with each other, as shown in Figs. 2 and 5, the tongue 3 of each section being received by a slot & provided in a semi-annular flange 5 of the opposite section. A semi-annular rim 6, having either two or three faces a, is

Specification of Letters Patent.

Serial No. 106,455. 1

provided on the outer periphery of each section at the inner face thereof, each of said rims extending outwardly therefrom, both semi-annular rims 6 taken together, when the sections are in interlocked relation with one another, forming a square or hexagonal nut or wrench engaging surface, as shown in Fig. 1, for the purpose hereinafter described.

Each tongue 3 has slightly tapered sides 1) for the ready reception thereof by said slots 4c and also to cause a slight binding action between said tongues and their respective slots at the points of contact between their side walls 6 and respective end walls 0 of said slots 4.

Said section 2 differs in two respects from said section 1, in that it is provided with an annular recess or concavity 7 into which a washer of desired composition Or suitable packing is inserted for the purpose of preventing leakage between said sections. 1 and 2, and in that it is provided with screwthreads 8 upon its outer peripherical surface, which threads engage corresponding threads provided upon the inner peri'pherical surface of a collar 9, which collar is screwed into position after said sections are in interlocked relation with each other for the purpose of preventing separation of the sections. Said collar is further provided with an internal annular recess 10 at its inner end, which receives the flange of the oppositely disposed section 1 to that upon which the same is screwed, as before described.

The outer ends of the tongues 3 are cut to conform, as seen in Figs. 3 and at, to the design of their respective rims, (see dotted lines in Fig. 1) whether such rims are square, hexagonal or curved, when taken together, said curved rims being illustrated in Fig. 6.

In that form of the invention as illustrated in Fig. 6 we dispense with said collar 9 and in lieu thereof provide perforated lugs 11 one integral with the end of the tongue 3 of one of said sections while the other is integral with the rim 6 of the opposite section.

In this form the outer edge of the rims and ends of the tongues are constructed curved. Said perforations in the lugs 11 are for the purpose of receiving nut and bolt connections and act as a substitute, when taken in connection with said lugs, for said collar 9.

Both of the sections are suitably internally threaded whereby the end of hose-sections are in the usual manner secured thereto.

In that form of the invention illustrated in Figs. 7 to 10, we substitute, in lieu of the tongue 3, a pair of horns 3 and in lieu of the slots 4, a pair of perforations 4' registering with and receiving the'horns or lugs 3, When the device is in coupled position. Each hornpr lug through which a pin 5 extends thereby securing the horns or lugs against removal from their respective perforations, said pin contacting the outer surface of the coupler.

Although we have specifically described the novel features of construction, combination and arrangement of the various forms of our invention, yet we do not confine ourselves to same but reserve the right to make such changes therein as do not depart from the spirit of the invention and'as fall within the scope of the appended'claims.

Having-described-our invention, we claim as new# 1. In a coupler of the kind described comprising two inter-locking sections, each of which sections is provided witlra semi-annu-' lar flange and a semi-annular rim, each of said semi-annular flanges provided with said slot therein, a tongue provided on each section on the opposite side of the face thereof to that of the fiange,,the tongue of each section being receix edby the slot in theflange of the opposite section, and means to secure the sections against separation after being placed into interlocked relation with one another, one of said sections being provided with an interior annular concavity or recess, a washer being-inserted into said concavity when the sections are connected together,

is provided with a perforation said semi-annular rims having a plurality of faces provided on their outer periphery, each of said rims extending outwardly from its respective section, the faces of said semiflange and rim being adjacent itsinner face,

each flange being provided with a slot therein, a tongue extending from the opposite side of the same face to which the flange and rim are formed integral, the tongue of each section being received by the slot in the flange of the other section when said sections are in interlocked relation'with one another, a collar threaded on said externally screwthreaded section, said collar being provided with an internal recess at its outer end which recess is for the reception of the'flange of the opposite section to that to which the same is screwed, and means comprising packing to prevent leakage at contacting inner faces of the sections.

In testimony whereof we aflix our signatures in the presence'of two witnesses.
